How do Mexicans refer to the wedding ceremony and the celebration following the wedding? I am attending a Mexican wedding and would like to refer to these events properly.
Personally, for the first part I'd use "Recepción", it's more adequate in all cases, because the word "Banquete" can be awkward if the mentioned event is actually a small and humble one.
If they are Mexicans is probably that the mass will be in a catholic church, that's a "misa" [mass], and then the party will be just the party because "boda"[the wedding] envolves both mass and party but it's normal to call it "la boda" since a lot of people just go to the party "la boda" is accurate for the party, if the day after they make another party in the morning will be "lavado de olla" [Whashing pot] or "recalentado" [reheaded] depending on what part of Mexico they are. "Recepción" and "Banquete" are American concepts but since they live in the US I assume that it will be understood.
